SECTIONAL SHAKING AND DUMPING GRATE.

Specification of Letters Patent.

Patented m 26, 1914.

Application filed October 1, 1912. Serial No. 723,289.

To all whom it may concern:

Be it known that .1, CHARLES '1. Con, a citizen of the United States, and a resident of Kearney, in the county of Hudson and State of New Jersey, have invented certaln new and useful Improvements in Sectional bhaking and Dumping Grates, of whlch the following is a specification.

This invention relates to a sectional shaking and dumping grate.

It is an improvement of my invention filed January 30th, 1909, Serial Number 475,0 91, and is characterized by novel dumping frames with grate sections, and novel means to secure'the latter in said frames to prevent their detachment when using the grate.

In the accompanying drawings, Figure 1 represents a plan view of a grate exemplifying the invention with a fragmentary portion of a furnace, Fig. 2 is a partial front view and section of Fig. 1 on the line 2, 2, Fig. 3 shows a side view of one of the intermediate side bars of the grate, Fig. 4 represents a top plan View of Fig. 3, Fig. 5 shows a fragmentary side view of an end side bar, Fig. 6 shows an enlarged fragmentary front view of a dumping frame of the invention with a section as on the line 6, 6 of Fig. 8, Fig. 7 is a top plan view of a dumping frame with its grate sections, Fig. 8 represents an end view of the dumping frame, Fig. 9 shows a partial section of .Fig. 6 on the line 9. 9. Fig. 10 shows a section similar to Fig. 9 with a modification, Fig. 11 represents a top plan view of a modified dumping frame, Fig. 12 is an end elevation Fig. 11 and Fig. 13 shows a side View of a portion of the end side bar with fragmentary portions of dumping frames.

The invention comprises a furnace ha'ving intermediate side bars 20 and end side bars 21. The bars 20 hav sockets with the vertical walls 23, 24 and the cylindrical bearings 25 of greater diameter than the distance between the said walls. A lug 26 intermediate of the sides of the bar and extending from the upper face thereof forms the wall 24. The bars 20 also have sockets with the 33, 34 and the cylindrical bearings 35 of greater diameter than the distance between the latter walls. A leg 36 extend from the topand outer face of the latter ha; and

forms the wall 34. The bars 21 also have the sockets with the cylindrical bearings 38 of a diameter equal to the distance between the walls 39 thereof. In the ends of the 0 said bars are vformed dovetailed sockets 42 that engage lugs 43' of the cross braces 44, the latter each having corrugations shown at 45 and 46. Between the said side bars are located the dumping frames comprising 5 each the end walls 51 which are connected by the top flange 52, indented or corrugated in the edges thereof as shown at 53 and- 54. The raised portions 53 of the edge of the flange of one frame interlocks with the de- 7 pressions of the edge of the flange of the frame next adjacent, and at the ends of the grate the raised portions 53 of the dumping frames interlock with the depressions 46 of the cross braces 44. The said flange 52 has formed therewith the inclined longitudinal bearing brace 55 and the shouldered longitudinal bearing brace 56. A lower longitudinal connecting brace 57 extends between the end walls 51 and'has extending therefrom the hooks 58 and the forked leg 59, The end walls 51 have each extending therefrom the cylindrical trunnions 60 with the segmental portions having the flat faces 61, which latter are vertical when the dumping 35 frames are in their normal positions. The said trunnions are in this instance shown with their centers'in'a-vertical line inter-' secting the ends of the flanges 52, and are supported on the bearings of thesockets in the bars. Connecting braces 62, 63 extend between the flange 52 and the brace 57. Grate sections are located between the walls 51 and are supported on the bearing braces 55 and 56. Each grate section comprises the bars 66 that are formed with theconnecting braces 67. The bars 66 are curved at their-upper edges and at their rear ends have formed therewith the heels 68, that bear and lock with the braces 56, and at their front ends they have the incliriedbearing surfaces 69, that bear on the braces 55.

From each grate section extends a lug 70 with a hook 71, and a connecting link 72 connects this hook with one of the hooks 58 5 extending from the connecting brace 57. Pins 73 supported by the legs 59 ofa number of the dumping frames are joined by the connecting bar having th" upper member 75 and the lower member 76. From the 1 latter extends a lug 77 to which is secured a reach rod 78, by means ofthe jam nuts 79.

From the front end of each reach rod extends a forked connection 80. To the front of the furnace are pinned the links 8,6, and ashaking link 87 connects each link 86 with the said forked connection.

In Fig. lO'the grate section is modified and from one of the bars 95 thereof, extends a. lug 96 with an opening 97 for the connecting link 72. In Figs. 11 and 12 the dumping frame is shown with its top flange devoid of corrugations in the edges thereof.

To use the grate the operator preferably by means of a shaking bar, rcciprocates one of the shaking links 87, and thereby one of the sets of dumping frames is swung. To

locate the trunnions of the dumping frames on their bearings, they do not require to be tilted when passing through the parallel walls of the sockets.

- When the dumping frames are swung as shown in the rear portion of the furnace and particularlyin Figs. 1, 2 and 13, the ends of the trunnions 60 extend beyond the vertical wallsQ and 34 of the sockets in the intermediate side bars 20 and end bars 21, thereby locking said trunnions and consequently their dumping frames with said side bars. This avoids the necessity of tilting the dumping frames when they are put in place. Some of the bearingslike 28 and 38 in the said bars have their walls separated a distance equal to the diameters of their hearings, to show that the special dumping frames can be used with such bearmgs.

The trunnions 60 being formed with their full cylindrical bodies adjacent to the walls 51 of the dumping frames and only segmented at their ends, form strong and novel gtlructures not easily broken by rough han- Thecoaction of the interlocking flanges of the dumping frames, as well as the interlocking of the flanges of the end dumping frames with the corrugated cross braces 44:, provides means to cut any caked fuel that may be formed upon the grate, and also allows the frames to be close enough together to be enabled to use very fine fuel.

It will be noted that the dumping frames have no cross walls between the end walls 51, that two of the grate sections abut with their outer end walls against the walls 51 of the dumping frames, and that the other ends of the outer grate sections abut against the inner grate section in each dumping frame.

Having described my invention what I desire to secure by Letters Patent and claim is:

1. In a grate frame comprising upper longitudinal bearing braces, end walls connectmg said braces, a lower connecting brace connecting said end walls, a leg extendingfrom the lower brace, grate sections supported upon said upper braces, the outer ends of a pair of said grate sections abutting against the end walls of the grate braces at the upper portion. thereof, end

walls connecting the braces, a lower connecting brace between the end walls, hooks formed on the lower brace, grate sections supported on said braces of the upper portion of the frame, a hook formed on each grate section and a link connecting the hook of each grate section with one of the books of said lower connecting brace.

4. For a grate the combination of supporting bars having bearings formed therein, cross braces locked with the bars, dumping frames having trunnions extending from the sides thereof and the latter supported on the bearings of said supportingbars, each dumping frame having a lower connecting brace with a plurality of hooks extending therefrom. grate sections each having a hook extending therefrom sup ported on each dumping frame, a link connecting the hook of each grate section with a hook on said lower connecting brace of its dumping frame and means to swing said dumping frames with their grate sections.

Signed at the borough of Manhattan in the county of New York and State of New York. this 24th day of September A. D.
